Natural starch is mainly composed of two major components, amylose and amylopectin. The composition ratio of these two components is different, and the sensory quality and processing properties of food are also completely different. With the development of society, the use of amylose is more and more extensive. It is of great practical significance to carry out amylose determination. The significance of amylose determination from the aspects of grain inspection and high amylose crop breeding is as follows.
1. The significance of amylose determination in food inspection
The content of amylose is an important factor affecting the sensory quality and processing characteristics of grain. It is closely related to the gelatinization, gelation, viscosity, solubility, swelling ability, digestibility and resistance of starch. High and low is an important indicator for evaluating food quality. Therefore, the determination of amylose is of great significance for evaluating food quality, guiding food processing and rational utilization of starch. In the food testing, the determination of amylose content has strict standards and requirements. In order to carry out the testing work better, modern methods are mostly measured by instrumental method, that is , directly measured by amylose analyzer .
2. Significance of amylose determination in high amylose crop breeding
Amylose is widely used as a food additive, thickener, fixative and coating agent, as well as a protective layer for products that have good insulation against oxygen and grease. It is a modern food, medical, and materials. Important products that are needed in many industries such as papermaking and packaging. Therefore, in order to meet market demand, the agricultural field needs to strengthen research on high amylose crop breeding. The use of amylose analyzer to accurately determine the amylose content can better carry out the selection and breeding of high amylose crops, and effectively improve the efficiency and quality of breeding, and promote the development of emerging industries with high level of breeding.
